Satori is a character with a rather complex and multi-faceted personality. She is isolated and appears cold and indifferent to strangers, a defense mechanism stemming from her mind-reading ability which causes humans to shun her. However, deep down lies a lonely heart that yearns for connection, something especially evident in her boundless love for her younger sister, Koishi. Her sarcastic, intelligent nature and her blunt, often brutally honest way of speaking are also her most striking traits.
